Grab your propane torch. Open the valve so that some propane escapes from the nozzle (but don't light it). Start the car and let it idle.
Play the nozzle over any areas where there could be a vacuum leak, and pay attention to the idle speed. If the idle speed changes noticeably, it's probably sucking in the propane and burning it. This should pretty well pinpoint the leak.
